EXOSHELL Energy – energy-efficient building envelope, virtually energy self-sufficient

The EXOSHELL external support structure creates ideal conditions for generating renewable energy and ensuring the self-sufficiency of the entire system. Photovoltaic modules can be flexibly integrated into the decoupled facade or installed on the retention roof, thereby significantly increasing the available surface area for energy generation. Storage systems store the generated energy, allowing the building’s technical systems to operate nearly self-sufficiently. A sustainable and cost-effective solution that positions real estate for the future.

Smart Energy Use for Lower Operating Costs

EXOSHELL is designed to cover a large portion of its own energy needs—a clear advantage in terms of operating costs and sustainability. The photovoltaic modules utilize nearly all suitable facade and roof surfaces, while integrated storage systems reliably store the energy generated.


The insulation properties and optional shading modules further enhance the building’s energy efficiency by reducing heat loss and providing effective shading. The energy generated can also be used directly to power charging stations—an attractive added value for modern residential and commercial properties.

Benefits that are compelling from both an economic and energy perspective

Renewable energy generation, smart storage technology, and thermal optimization are combined in a single system that both reduces operating costs and opens up new revenue opportunities. This creates measurable added value for both owners and tenants—both environmentally and economically.

Energy Efficiency & Operating Cost Optimization

  • Decentralized energy generation: Photovoltaic modules generate usable energy directly on the building andsignificantly reduceCO₂ emissions.
  • Peak load reduction through storage and energy management: The combination of storage and energy management systems smooths out load profiles and lowers ongoing utility costs.
  • Thermal comfort and lower cooling loads: Shading elements and optimized facade zones reduce heat gain, increase comfort, and lower energy demand for cooling.
  • Zone-based control of facade elements: Different areas of the facade can be regulated separately, allowing lighting and shading conditions to be adjusted as needed.

Revenue Potential & Value Appreciation

  • On-sitepower models for tenant electricity or energy contracting: The energy generated can be supplied on-site or used profitably within appropriate models.
  • Decarbonized mobility as a location advantage:E-charging stations for cars and bicycles can be powered by the energy generated, thereby increasing the property’s appeal.
  • Revenue potential from charging revenue: Charging points open up new business models and enable grid-friendly load management with additional economic benefits.
